Stylish Metal PCB Enclosure Design

I require an enclosure design for a small PCB 121x90mm. It will be sheet metal fabricated, so an L-shape or clamshell is probably the best. It will have some slots cut out for USB ports, audio port etc... (Budget: $250 - $750 AUD, Jobs: 3D CAD, 3D Design, 3D Modelling, AutoCAD, CAD/CAM, Manufacturing Design, Product Design, Solidworks)
